A funny, but somewhat short list of quotes about (mainly disparaging) programming languages by people famous enough that it counts.
Of course some of the best are by Dijkstra.
“It is practically impossible to teach good programming style to students that [sic] have had prior exposure to BASIC; as potential programmers they are mentally mutilated beyond hope of regeneration.”
There’s nothing in there about Objective-C, but I’m sure there’s got to have been some interesting things said about it.
